SEAMING' MECHANISM;

Application filed A ust 6, 1924; Serial no. 730,412.

This invention relates to seaming mechanism for uniting containers and covers, and has for its main object and feature the provision of simple and easily adjustable means for actuating the seaming means, particularly though not exclusively, to be used in connection with non-round containers, and so arranged that the seaming tool may be driven at all times notwithstanding the in-and-out movement of the seaming tool toward and away from .the work.

In the accompanying drawings the invention is disclosed several concrete and now preferred forms in which:

Fig. 1 is a vertical section through a seaming mechanism embodying the invention in a device in which the work stands still and the seaming tools travel around the work in an orbit. I I

Fig. 2 is a horizontal sectional View on the plane of line 22 of Fig. 1. i v

t Fig. 3 is a horizontal sectional view on the plane of line 33 of, Fig. 1.

Fig. .4 is a vertical sectonal view on the plane of irregular line 1.4;' of Fig. 2.

Fig. 5 is a perspective view of the floating member that rotates the seaming tool.

Fig. 6 is a perspective view of the sleeve and plate that carries the seaming tool.

Figs. 7 Sand 9 are views similar to Fig. 3, but with some of the parts removed; showing the movement of the floating member during the operation of the device.

Fig. 10 is a vertical sectional view ofv a seaming meo hanismfshowing a modified form of the invention in which the work rotates.

Referring to Figs l to 9 inclusive, 1 indicates a chuck to engage cover 2 of container 3. In the present instance this chuck is non-rotating. The container here selected for illustration is non-circular and specifically substantially square as indicated in outline in Figs. 3, 7, 8 and 9. The out line of the seaming tool 4 is complementary to that of the oontainen The problem that this inventionseeks tosolve in an effective and simple vay is to effect relativemovement between the workand theseaming tool, to rotate the seaming tool and to impart an in-and-out movement to the seaming tool without bringing the elements of the driving mechanism out i of mesh,' the; parts heing also readily adjustable and. removable. Of courseone may say. that that is the prob-- lem of all seaming meohanism and is tion can be used'in connection with circular containers and tools. 7 In the form shown in Figs. 1' to 9 inclusive the relative movement between the work andseaming'tool or between the chuck and seamer head'is obtained by causing the work to stand still and the seamer head to travel in anorbit around'the work. As shown in the drawings chuck 1 is mounted on stationary shaft 5 and keyed to the same shaft is a gear6 concentric with the chuck. .7 indicates a seamer head mounted concentric with shaft 5 and driven in any suitable way as by meansofbevel gears 8 and 9. 10 is a cam concentric with the seamer head, chuck and shaft '5." f p The number of seaming tools may vary, but since theyare constructed alike a description of: one will suifice. 11 indicates a supportcarried bythe head, and extending eccentrically through said support is a crank shaft 12' having at one endan' arm 13 provided with a. cam roll 14 engaging cam 10. At its other end said crankshaft is provided with a crank pin'l5carrying the seaming tool 4." From this itwill be understood that rotation of cam 10 (here effected by sleeve 16 and bevel gears 17 and 18) willc'ause the crank shaft to rock and will move the seaming tool toward or away from the work. The means for rotating the seaming tool are as follows: Mounted loosely on support 11 is a gear 19 that is in constant mesh with gear 6 onshaft 5. Interposed between the seaming tool and gear 19 is a floating member 20 and this floating member'forms by means of pins and slots, thev driving'connection between gear 19 and seaming tool 1- so that the latter is constantly rotated from the former crankshaft. In thespecific form here disclosed these parts are constructed as follows:

Mounted on crank pin 15 is a sleeve member 21 having a circumferentialplate 22. Seaming tool 4: is secured-to the underside of plate 22 by means ofscrews 23 or otherwise. 2-1 is a screw the head of'which supports the lower end of sleeve 21 and is tapped'into the end of crank pin 15. In the up er surface of plate 22 are two radial s ots 25. Resting on this plate is floating member or disc 20 which at itsunderside is provided with shoes 26 to engage slots 25. In its upper surface said disc has two radial slots 27, at right angles to shoes 26, and engaging with these slots are two shoes 28 carried by gear 19. It will now be understood that rotation of the seamer head carries support 11 in an orbit around the chuck and that by reason thereof gear 6 rotates gear 19, and, there being a difference in speed between seamer head 7 and cam 10, the crank shaft will be rocked to thereby bring its crank pin, and therefore the seaming tool, toward or away from the work. Rotation of gear l9 will be transmitted to floating member 20, and the latter will, in turn, drive plate 22 and seaming tool 4t. The floating member will, as indicated in Figs. 7, 8 and 9, accommodate itself by sliding with respect to shoes 28 of gear 19 and with respect to slots 25 of plate 22. The positions shown in Figs. 7, 3 and 9 vary by one-eighth of a revolution and the seaming tool is supposed to be traveling in an orbit around the work in the direction indicated by the arrows. F or the sake of convenience and to preserve the symmetry of the drawings on the sheet the orbital movement of the seaming tool around the work is represented by varying the position of container 3. I If it is desired to replace seaming tool 4:, or any of the elements from gear 19 down to the seaming tool, itis only necessary to remove screw 24. Support 11 is seated in a circular opening 29 in the seamer head and is provided with arms 30 beneath said seamer head. Said arms have curved slots 31 through which extend bolts 32 into the seamer head. Carried by the scanner head is a bracket 33 in which is a rotatable member 34; in threaded engagement with one of the arms 30. It will be apparent, bolts 32 having been loosened, that, by turning member 34, support 11 will be turned in. recess 29. This will alter the angular relation of arm 13 between crank shaft 12 and cam 10 and will adjust the position of the crank pin to move the seaming tool nearer to or farther away from the work so as to vary the tightness of the seam. v

' In Fig. 10 is shown a modification in that chuck 1 and gear 6 are mounted upon a shaft 35 that rotates, motion being imparted thereto by pulley 36. Seamer head 7 is here stationary and cam 10 is driven by means of bevel gears 37 and 38. The seaming tool and its supporting means are the same as in the first form of the invention.
